TECHNICAL FIELD

This disclosure relates generally to website design and testing. More particularly, embodiments disclosed herein relate to a system, method, and computer program product for rendering a website on multiple devices simultaneously and routing the results to a user as an analysis report and/or images.

BACKGROUND OF THE RELATED ART

Traditionally, websites have been designed for viewing on desktop and laptop computers having standard display sizes. Accordingly, it has been relatively easy to design websites for display on such devices. However, the proliferation of devices such as smartphones and tablet computers has resulted in a corresponding proliferation of display sizes and aspect ratios.

A typical procedure for ensuring that a website displays properly on a device has required, firstly, that the device be in a tester's possession. A website URL (Uniform Resource Locator) provides a location of a web page of the website. References herein to a website URL refer to a URL of the website that references a web page of the website. Once the device is in the tester's possession, the device's browser may be launched and the website URL (Uniform Resource Locator) typed into the browser (typically through a touch screen). The browser may then display the website on the screen. Once displayed, the tester may capture an image of the screen. The tester then may scroll down the website and perform another capture of the screen. This process is repeated for each screen page of the website. The precise process of obtaining such a screenshot and the number of screenshots for a website may vary per device and operating system. The screenshots for the website under testing may then be saved or exported by using a cable or wireless connection to a computer or sending an e-mail from the device. The resulting device images are then stitched together using photo editing software.

As can be appreciated, for a wide spectrum of devices, this can be an expensive and time-consuming proposition. Furthermore, the devices must be in the physical proximity and be physically manipulatable by a user. Advances in technology continue to bring challenges to website design and testing. Consequently, there is always room for innovations and improvements.

SUMMARY OF THE DISCLOSURE

Embodiments disclosed herein generally relate to devices that physically render web pages of a website in a testing environment. Due to variations and revisions of web pages and devices that display the web pages, the particular physical rendering and display of multiple web pages by multiple devices often yields unpredictable results. A website designer designs one or more web pages for display by multiple devices that display web pages, such as smart phones, tablet computers, laptop computers, and desktop computers. Often the devices that will access the website differ in one or more of numerous ways, such as by different operating systems, different embedded and integrated browser applications, different physical display sizes, different display resolutions, different color palettes, and different font libraries. Furthermore, many of the foregoing features of the devices are often updated or otherwise changed on a physical and/or software (including firmware and operating systems) basis. Additionally, many websites often change the content, format, graphics, or other design features.

Against this backdrop of changing devices, changing web pages of websites, and the unpredictable results of physical rendering and display of a web page on the devices, physically testing the web pages on devices of interest in an on demand environment presents a tangible and concrete technical problem. Embodiments herein provide a technical solution to overcoming the physical limitations of activating the devices for testing the web pages and returning test results to a user. Furthermore, time constraints to successfully implement web pages across multiple device platforms while utilizing a minimal amount of human resources benefits from embodiments of the technical solution described herein. In at least one embodiment, the system and method can remotely test multiple web pages, such as 10 or more, within, for example, seconds of receiving a URL.

Additionally, embodiments disclosed herein relate generally to the field of website design, specifically in the context of a designing a website for viewing on mobile devices. In some embodiments, a system includes a web application, a device service in communication with a plurality of devices, and a device application running on the devices. A tester may use the web application with a particular device service to select devices and input an URL of a website for testing. The URL and list of selected devices is provided via the web application to the device service, which causes the selected devices to load the website at the designated URL using a browser embedded in or integrated with the device application. In some embodiments, device applications running on the selected devices load the websites and provide images corresponding to entire pages for a given URL (not just what fits on a screen) to the web application via the device service.

In some embodiments, a device application may include a native browser that loads a specific website and implements a screenshot function for capturing the entire web page of a website. The screenshot function may determine when a web page is loaded and when an image of a particular screen of a page of the website should be captured; once an image of the screen is captured, the device application automatically scrolls down to the next screen of the web page and performs another screenshot capture, until the entire web page is captured. The images are transmitted to, for example, requesting tester (e.g., a web application) where the images are automatically stitched together into a single image. In at least one embodiment, the images are transmitted to an application that performs a captured image-to-target image comparison analysis as described in the Berry patent application.

Embodiments disclosed herein can provide many advantages. For example, embodiments allow a tester to test multiple devices at a given time and without having to individually activate and configure the device's web browser. Further, the device application is able to capture an image of an entirety of a web page rather than individual screenshots.

These, and other, aspects of the disclosure will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings.

DETAILED DESCRIPTION

The disclosure and various features and advantageous details thereof are explained more fully with reference to the exemplary, and therefore non-limiting, embodiments illustrated in the accompanying drawings and detailed in the following description. It should be understood, however, that the detailed description and the specific examples, while indicating the preferred embodiments, are given by way of illustration only and not by way of limitation. Descriptions of known programming techniques, computer software, hardware, operating platforms and protocols may be omitted so as not to unnecessarily obscure the disclosure in detail. Various substitutions, modifications, additions and/or rearrangements within the spirit and/or scope of the underlying inventive concept will become apparent to those skilled in the art from this disclosure.

FIG. 1 illustrates an exemplary environment in which a website rendering method and system disclosed herein may be implemented. In the example illustrated, the system 100 includes a user device 101 running a web application 102; a device service 104; and a device farm 106 including one or more devices 108 a-108 n running device applications 110 a-110 n. The device applications 110 a-110 n may be specific for each device's corresponding operating system (e.g., iOS, Android, Windows Phone, etc.).

The user device 101 may be embodied as a personal computer or laptop computer, for example. The web application 102 may be an application program including a user interface and capable of communicating with the device service 104. In some embodiments, as will be discussed in greater detail below, the web application 102 may allow a tester to input an URL for testing and may select corresponding devices in device farm 106 to test the URL.

The device service 104 may be implemented on one or more servers 103, for example, a cloud-based service providing access to the device farm 106 for a fee. The device service 104 communicates with the devices 108 a-108 b, sending them the URL received from the web application 102. The device applications 110 a-110 n cause their integrated web browsers 112 a-112 n to open the web page. The device applications 110 a-110 n then capture images of the web pages and transmit them via the device service 104 to the web application 102.

FIG. 2 illustrates a storyboard representation of user interfaces and tester interaction therewith in greater detail. In particular, at 202, a web application (e.g., the web application 102 shown in FIG. 1) allows a tester to enter an URL that they would like to see the website rendering. The tester can then select the devices for which the website will be rendered on, as shown at 204.

In some embodiments, the request to a device service (e.g., the device service 104 shown in FIG. 1) is sent as soon as a device is selected. In this way, the lag time for the user to see the resulting images may be shortened, if not eliminated entirely. As shown at 206, after the tester is finished choosing their devices, a page is presented which immediately begins to show a rendered image from the device and continues to show the progress being made while the image is processed. The complete websites as rendered on the user devices (e.g., user devices 108 a-108 n shown in FIG. 1) are then displayed to the tester, at 208. After the website images are rendered, in some embodiments, the tester may optionally share and/or export them.

Advantageously, in some embodiments, the images for the websites are the entire page for the given URL, not just what would fit on a device's screen. However, the user may want to see how much information fits on the device screen. Consequently, in some embodiments, the web application may show one or more representative lines, such as a fold line, so the user can conveniently view possible page divisions.

For example, shown at 302 in FIG. 3 is an example of a website capture on an iPhone 5S device. The fold line 304 denotes where a new screen view begins. (In operation, an end user of the device would scroll down to view the remainder of the website). A similar website capture is shown at 306 for the Galaxy 5S device, with its fold line shown at 308.

In some embodiments, the rendered image may be very large, owing to the high resolution (DPI) of some mobile devices. In this case, the web application 102 may show a scaled image and allow the user to click the image to see a full screen image. This gives the user to quickly scan the image for anomalies, while still being able to zoom in.

Some embodiments may also provide the user with the ability to compare one or more images to highlight a possible problem or differences from one version of the website to the next. This feature may show one or more image and use color and/or boxes around differences. The areas that are the same may be slightly dimmed to place more emphasis on the differences.

In some embodiments, the device service 104 functions as a middleman between the web application 102 and the physical devices 108 a-108 n. In particular, in some embodiments, the device service 104 provides secure REST API calls: (i) Type of devices that are available to render websites; (ii) Status of the devices (availability, working on a rendering (job), etc.); and (iii) Cancel a job on a device.

In some embodiments, the web application 102 makes secure REST API calls to the device service 104 to request a URL for a given device. The device service 104 then creates a job for a device. If all devices are busy, the callback for the REST API will provide status of the job. When the job is complete, the callback will return and tell the web application 102 it is complete and provide the image for viewing.

Below is a representative sample and description of the REST API for creating a job:

### POST /api/v1/jobs

Posts a new job.

-   -   Required fields:         -   ‘requested_device_type’: The device type requested (‘iPhone             5s’ ‘iPad Air’ . . . ’)         -   ‘url’: The requested URL         -   ‘orientation’: ‘portrait’ or ‘landscape’         -   ‘format’: ‘jpg’ or ‘png’         -   ‘callback_url’: url to call when a job is being processed             -   The callback is used (via http POST) to notify of status                 changes for a job and to send the image to the                 requesting server. The images are ephemeral on Mobilizer                 Capture Service, so you should save the image from the                 callback.             -   Callbacks can be made multiple times during job                 execution:                 -   1. To indicate status changes                 -   2. Once complete, a callback will be made with a                     time sensitive URL to the image. The URL requires                     the same authentication.

Callback Contents (Content-Type Application/Json):

{   “job” : id,   “status” : “loading|complete|failed”,   [“device” : {     “name”  : “{device name}”,     “os”  : “{operating system - iOS, Android, ...}”,     “os_version” : “{os version}”   }],   [“url” : {image url when status == “completed”}],   [“error” : {error code when status == “failed”}] }

-   -   Other possible fields, currently not used:         -   ‘requested_os’         -   ‘requested_os_version’     -   Returns:         -   JSON representation of the full job (including the newly             created ‘id’)

As the cloud service 104 creates jobs, in some embodiments, it sends commands to the device application 110 a-110 n being queued over TCP/IP. The message traffic over TCP/IP contains the URL to be rendered.

In some embodiments, the device application 108 a-110 n is a native application for each device 108 operating system (“OS”) and is used to capture the website on that device. The native application may be deployed to devices that have network connectivity to the device service. In some embodiments, the device application can support multiple concurrent website renderings. The number supported can vary based on the computing power of the device. In some embodiments, the website image may be created as a full-size rendering of the website in either PNG or JPEG format, depending on the requestor.

Turning now to FIG. 4, a flowchart 400 illustrating operation of a system implementing a method according to some embodiments disclosed herein is shown. At 402, a tester or user may input an URL of a website to be tested, as well as selecting the devices on which he wishes to run the test via a web application (the web application 102 shown in FIG. 1). The URL and selected device(s) are then sent to a device service (e.g., the device service 104 shown in FIG. 1), at step 404. As noted above, this may be done by the web application using a REST API call to the device service. At step 406, the device service may select the physical devices and transmit to those physical devices the URL of the website to be rendered, for example, using TCP/IP. In response, a device application (e.g., the device application 110 shown in FIG. 1) running on a physical device opens and causes an integrated browser to open and render the website of the requested URL on the physical device, at step 408. The device application then captures images of the entire website at the URL and transmits back to the web application via the device service, at step 410. It is noted that, in some embodiments, the devices may access more than one website at a time, i.e., in response to commands from the device service, multiple physical devices may render and return (in parallel in one embodiment) images of more than one website.

Further details on the operation of the device application(s) described above can be found in the accompanying Appendix which forms part of this disclosure.

FIG. 5 illustrates an overview of an example device application (e.g., device application 110 a, 110 b, . . . , 110 n shown in FIG. 1). As noted above, the device application receives from a device service (e.g., the device service 104 shown in FIG. 1) a website URL to render and returns the entire website at the URL. As shown, the device application may include an embedded browser (distinct from the device's standalone browser) and implements one or more components. These may include Initialization, Completion Detection, Capture and Page Scrolling, and Crash Recovery modules.

As will be discussed in greater detail below, the initialization module ensures that the embedded browser is reset every time is receives a request to render and capture a website. The completion detection module identifies when a website and individual components thereof, as finished rendering so that an image may be captured and returned to the requestor. The capture and page scrolling module serves to identify when a screen can be captured and when to scroll to the next screen to capture it. This may be repeated until the end of website content at the requested URL is reached. The resulting images are passed to the web application and, in some embodiments, stitched together by the web application. In one embodiment, the resulting images for the website at the URL may be stitched by the device application. Finally, the crash recovery module recovers the device application 110 from a browser 112 crash.

In some embodiments, a device application for capturing websites on a physical device may be provided for each device Operating System (OS). In some embodiments, the device application may be deployed to devices that have network connectivity to the image requestor (which can be a web application associated with an end user or a device service hosted on a server). Within this device application, a component waits for external requests to load pages and then proceeds to load and render the pages in a suitable image format depending on the request, such as PNG or JPEG format.

In some embodiments, to maximize device usage, the device application running on a physical device (e.g., a mobile device) may be able to support multiple concurrent website renderings. Depending on the mobile device's resources, specifically memory and CPU, for instance, multiple web browser instances can be spawned simultaneously to optimize device utilization. The number supported may vary based on the computing power of the device.

The initialization module is provided to ensure that the embedded browser starts in a “clean” state. In some embodiments, the following steps are performed for each site request:

-   -   The device is programmatically oriented to the requested         orientation (landscape or portrait.     -   A new browser instance is created based on the width and height         of the screen.     -   Browser caches and history are cleared to ensure cookies or         other browser state information doesn't affect the resulting         image. Often times the first visit to a page may render a popup,         such as an ad, and the image should reveal that behavior.

The completion detection module determines when the website has finished loading before the image(s) is captured (Blank spaces may appear if the image is captured before the website and all its components have finished loading). Detecting when a browser has completed rendering can be difficult with modern websites because content can be loaded through iFrames or asynchronously after the browser reports that the page has loaded. Browsers also tend to report completion before all of the content is completely rendered on screen.

To ensure that the page has loaded completely so that the entire site at the requested URL can be rendered to images, the device application in accordance with embodiments may perform the following steps:

-   -   Monitor all redirect requests and iFrame loads separately to         ensure they are completed.     -   Monitor the reported completion state from the browser and wait         for all content to load. Browsers report a percent completion         that is often erroneous, jumping between values because of         multiple redirects and iFrames being loaded.     -   Scroll through the entire contents of the page before rendering         to load any asynchronously loaded content and execute delayed         animations.

Operation of the completion detection module is shown more particularly with regard to the flowchart of FIG. 6. Initially, the page load starts, as shown at 602. If a completion percentage threshold is met, as determined at 604, then the completion detection module determines if the whole page has been scrolled down through, at 606. If not, the scrolling continues, at 608.

If the whole page has been scrolled down through, then the image is captured, at 612. If the end of the website is reached, as determined at 614, then the process ends, at 618. Otherwise, the next page is scrolled to, at 616, and its image is captured.

In 604, if the percentage threshold was not met, then at 610, the completion detection module determines if there has been progress in a predetermined wait interval. If so, then the process returns to 604. Otherwise, the process proceeds to 614, where it is determined if the end of the website has been reached. If so, the process ends, at 618. Otherwise, the next web page is scrolled to, at 616, and the image is captured, at 612.

In some embodiments, the capture and page scroller module scrolls down through a website and captures individual screen shots, passing them back to the requestor to be stitched into a complete image. In other embodiments, however, the stitching is performed at the mobile device itself.

However, mobile devices are memory constrained due to their form factor. The limited memory may prevent the ability to use available APIs in the web browsers to capture an entire website. While it is possible to render an image of an entire web page at the mobile device, doing so on long websites can use too much memory and crash the application. To prevent this from happening, embodiments perform the following steps:

-   -   Capture image on screen;     -   Scroll the browser to the next screen;     -   Repeat until scrolling has reached the end of the website         content;     -   Each image is passed to the requestor, and can be stitched         together

The crash recovery module is provided to recover the device application from a browser crash. (Anytime the embedded browser crashes, the application hosting the browser may crash as well).

Two factors rendering websites can cause the browser to crash:

-   -   1. The website may contain enough content or embedded content in         iFrames that will cause the browser to crash.     -   2. On some devices and OS's, the combination of the browser         rendering websites and scrolling on those sites can cause the         browser to crash.     -   Depending on the OS, one or more of the following mechanisms may         be used to recover from this state:     -   A background service running on the device separate from the web         browser capture application (i.e., the device application)         monitors the status of the web browser capture application. If         the application closes, a new application is spawned and         retasked to attempt the capture again. A configurable setting         may be used to limit the number of attempts to retry the         capture.

Built in OS mechanisms may also be used to either set the device application to be the sole application that may run on the device or the background service to always run. This ensures that on either a crash or device reboot, the background application will be executing without requiring external intervention.

In at least one embodiment, the programmatic implementation of the operations of FIG. 6 is a matter of design choice. The discussion herein generically refers to particular one of devices 108 a-108 n and device applications 110 a-110 b as respectively “device 108” and “device application 110.” In at least one embodiment, to determine a percentage of web page download completion, for a device 108 running an Apple iOS operating system, the device application 110 monitors three standard iOS notifications WebViewProgressEstimateChangedNotification, Web ViewProgressStartedNotification, and WebViewProgressFinishedNotification on _documentView.webView so as to monitor the percentage of the web page that has been downloaded. The device application 110 then waits until notified that the web page has reached a certain percentage download threshold, for example, at least reached 50% of a complete loading. Once the device application 110 receives that notification that the percentage download threshold has been reached, the device application 110 continues to monitor and wait for further progress in loading the page, setting a timer on each notification such that if no further progress occurs within a fixed interval, the device application 110 will begin to programmatically capture the web page. In at least one embodiment, similar operating system functions are available for other device 108 operating systems, and the device application 110 follows the same process for each device 108.

In at least one embodiment, to programmatically scroll to a web page end, for a device 108 running an Apple iOS operating system, the device application 110 executes a standard JavaScript method that is provided by the browser, window.scrollBy, to scroll the browser. For a device running an Android operating system, the device application 110 uses the standard Android WebView scrollTo and scrollBy methods to scroll the browser.

In at least one embodiment, to programmatically monitor redirect and iFrame loads, for a device 108 running an Apple iOS operating system, the device application 110 uses a standard iOS UIWebViewDelegate shouldStartLoadWithRequest method to monitor for redirects and iframe loads. In at least one embodiment, the device application 110 rejects any attempt to load the Apple AppStore, as indicated by a URL containing itunes.apple.com, or to load a page that is not served over http or https.

In at least one embodiment, to programmatically recover from a crash, for a device 108 running an Apple iOS operating system, the device application 110 uses Guided Access mode to provide crash recovery as Guided Access will automatically relaunch an application if it crashes. For a device 108 running an Android operating system, the device application 110 utilizes an application “captureservice,” which starts a second application “capture.” The capture application performs all of the actual web page capture, which is the operation that is most likely to cause a crash. The captureservice starts the capture application using the standard Android Intent mechanism and the two applications then communicate using a local socket. The captureservice expects to read a message from the socket that is sent by the capture application to indicate when the capture application has completed capturing the web page. If the captureservice fails to receive that message, the device application 110 assumes the capture application has crashed and will restart the application, which in at least one embodiment is the browser 112.

In at least one embodiment, to programmatically capture status monitoring of a web browser screen, for a device 108 running either an iOS or Android operating system, the device application 110 programmatically scrolls from a top to a bottom of the web page so as to ensure all elements on the web page are loaded before beginning the screen capture process. The device application 110 then programmatically scrolls down one screen at a time, capturing the screen display and saving the screen display as an image. This process repeats until the bottom of the web page, i.e. the last screen, is reached. For an Android operating system, the device application 110 delays for one second after capturing the image.

In at least one embodiment, to programmatically set a device application to be the sole application running applies to a device 108 running an iOS operating system and not with an Android operating system. In at least one embodiment, the device application 110 uses the iOS Guided Access feature of iOS as described at https://support.apple.com/en-us/HT202612.

FIG. 7 depicts an exemplary device 108. User input device(s) 710, such as a keyboard and/or mouse, are coupled to a bi-directional system bus 718. The input user device(s) 710 are for introducing user input to the computer system and communicating that user input to processor 713. The computer system of FIG. 8 generally also includes a non-transitory video memory 714, non-transitory main memory 715, and non-transitory mass storage 709, all coupled to bi-directional system bus 718 along with input user device(s) 710 and processor 713. The mass storage 709 may include both fixed and removable media, such as a hard drive, one or more CDs or DVDs, solid state memory including flash memory, and other available mass storage technology. Bus 718 may contain, for example, 32 of 64 address lines for addressing video memory 714 or main memory 715. The system bus 718 also includes, for example, an n-bit data bus for transferring DATA between and among the components, such as CPU 709, main memory 715, video memory 714 and mass storage 709, where “n” is, for example, 32 or 64. Alternatively, multiplex data/address lines may be used instead of separate data and address lines.

I/O device(s) 719 may provide connections to peripheral devices, such as a printer, and may also provide a direct connection to a remote server computer systems via a telephone link or to the Internet via an ISP. I/O device(s) 719 may also include a network interface device to provide a direct connection to a remote server computer systems via a direct network link to the Internet via a POP (point of presence). Such connection may be made using, for example, wireless techniques, including digital cellular telephone connection, Cellular Digital Packet Data (CDPD) connection, digital satellite data connection or the like. Examples of I/O devices include modems, sound and video devices, and specialized communication devices such as the aforementioned network interface.

Computer programs and data are generally stored as instructions and data in a non-transient computer readable medium such as a flash memory, optical memory, magnetic memory, compact disks, digital versatile disks, and any other type of memory. The computer program is loaded from a memory, such as mass storage 709, into main memory 715 for execution. Computer programs may also be in the form of electronic signals modulated in accordance with the computer program and data communication technology when transferred via a network.

The processor 713, in one embodiment, is a microprocessor manufactured by Motorola Inc. of Illinois, Intel Corporation of California, or Advanced Micro Devices of California. However, any other suitable single or multiple microprocessors or microcomputers may be utilized. Main memory 715 is comprised of dynamic random access memory (DRAM).
